2007 Featherlite 1075

I BOUGHT A NEW FEATHERLITE 4926 24' ALUMINUM CAR TRAILER WITH CARLISLE TRAIL RATED TIRES. THIS TRAILER HAULS MY 3240 POUND CAR, PLUS ABOUT 350 POUND OF GEAR PLUS THE TRAILER THAT IS 3410 POUNDS EMPTY. WITH TWO 4800 POUND RATED AXLES AND HAVING A RATING OF ABOUT >3000 POUNDS PER TIRE THERE WOULD BE A SAFE MARGIN (>12,000# TIRE RATING ON 9600# GVW WITH AN ~7000# LOAD). I NEVER HAD ANY HINT OF TIRE ISSUES UNTIL THIS LAST TRIP. ALSO, THE TIRES ARE COVERED IF THE TRAILER IS PARKED FOR MORE THAN OVERNIGHT. WE LEFT ON SATURDAY, JUNE 12, 2010 FROM FLORIDA HEADING TO BOWLING GREEN, KY. WE LOST THE FIRST TIRE (LEFT SIDE ' FORWARD) IN NORTHERN GEORGIA AND PUT ON THE SPARE. WE STOPPED IN RINGGOLD, GEORGIA THAT NIGHT. ON SUNDAY, JUNE 13, 2010, I BOUGHT AN LT 235/85-R16 TIRE AND HAD IT MOUNTED ON THE RIM FROM THE FAILED CARLISLE TIRE AND SAVED THE FAILED TIRE. WE PUT THE NEW TIRE ON IN PLACE OF THE SPARE. WE THEN LEFT FOR BOWLING GREEN, KY, ARRIVING ON JUNE 13, 2010 WITHOUT FURTHER INCIDENT. GIVEN THE LOSS OF THE FIRST TIRE, I DECIDED TO GET ANOTHER SPARE (WHICH I EVENTUALLY NEEDED). I PURCHASED ANOTHER RIM FROM AND HAD ANOTHER LT 235/85-R16 TIRE (TO MATCH THE OTHER PURCHASED TIRE) MOUNTED ON THE NEW RIM. ON SUNDAY JUNE 20, 2010, I CHECKED THE TIRE PRESSURES IN ALL TIRES INCLUDING THE SPARES, AND LEFT FOR HOME. IN TENNESSEE, ~7 MILES AFTER LEAVING A REST STOP ANOTHER CARLISLE TIRE FAILED (LEFT SIDE ' REAR). WE PUT THE NEW SPARE ON AND CONTINUED ON. WE THEN LOST THE RIGHT SIDE ' REAR CARLISLE TIRE IN MIDDLE GEORGIA. I PUT ON THE ORIGINAL SPARE AND WENT ON TO PERRY, GEORGIA WITHOUT INCIDENT. I BOUGHT TWO MORE LT 235/85-R16 TIRES AND HAD THEM MOUNTED ON THE RIMS WITH THE FAILED CARLISLE TIRES. WE REMOVED THE REMAINING CARLISLE TIRE AND ORIGINAL SPARE AND PUT ON THE NEW LIGHT TRUCK TIRES AND NO FURTHER PROBLEMS. *TR
